Extension South: Bridge 11 – Boots & spades on the ground

The Northampton & Lamport Railway’s version of Team Orange has started the preparation works on Bridge 11 project, which forms a key item on the Extension South to Boughton Crossing.

Since the end of March 2019 steps have been built at both ends of Bridge 11 to allow a temporary footpath & bridge to the west of Bridge 11. This is at the request of the council to keep the Brampton Valley Way open to pedestrians whilst Bridge 11 has its waterproofing replaced.

With the steps completed work has turned to the temporary bridge over the water course.
Once complete the initial preparation works at Bridge 11 will be complete. The main work to strip back the existing material down to the top of the arch brick work and drainage levels will commence at the end of May 2019, with the major work concentrated on week commencing 03 Jun 2019.

Please note once the major phase of the works start the Brampton Valley Way will be diverted for pedestrians and closed for other users such as cyclists. Signs have been posted around the site and the works are expected to take around 6 weeks.

The following schematic plan images show parts of the engineering plans which detail the new concrete deck and waterproofing that the works will install on Bridge 11. This will ensure the future use of the bridge for Brampton Valley Way users and the railway.
